Imidazolyl derivatives

ABSTRACT

The present invention is directed to imidazolyl derivatives of the formula: 
                 
 
where the substituents are defined in the specification, or a pharmaceutically acceptable salt thereof. The derivatives bind selectively to the somatostatin subtype receptors and elicit either an agonist or antagonist effect from the somatostatin subtype receptors. The derivatives are useful for treating a variety of diseases including acromegaly, restenosis, Crohn&#39;s disease, systemic sclerosis, external and internal pancreatic pseudocysts and ascites, VIPoma, nesidoblastosis, hyperinsulinism, gastrinoma, Zollinger-Ellison Syndrome, diarrhea, AIDS related diarrhea, chemotherapy related diarrhea, scleroderma, Irritable Bowel Syndrome, pancreatitis, small bowel obstruction, gastroesophageal reflux, duodenogastric reflux, Cushing&#39;s Syndrome, gonadotropinoma, hyperparathyroidism, Graves&#39; Disease, diabetic neuropathy, Paget&#39;s disease, polycystic ovary disease, cancer, cancer cachexia, hypotension, postprandial hypotension, panic attacks, GH secreting adenomas or TSH secreting adenomas.

BACKGROUND OF THE INVENTION

The present invention is directed to compounds and compositions containing said compounds which bind selectively to somatostatin receptor subtypes and the use of said compounds for treating medical disorders which are mediated by somatostatin receptor subtypes. Somatostatin (somatotropin release inhibiting factor, SRIF), a tetradecapeptide hormone, originally isolated from bovine hypothalami (Brazeau, P. et al., Science 179, 77-79, 1973) has been shown to have a wide range of regulatory effects on the release of a variety of hormones such as growth hormone, prolactin, glucagon, insulin, gastrin (Bloom, S. R. and Poldack, J. M., Brit. Med. J. 295, 288-289, 1987). In addition, antiproliferative properties (Reichlin, S., N. Engl. J . Med. 309, 1495-1501, 1983) have been obtained with somatostatin analogs in metastatic prostatic cancer (Parmar, H. et al, Clin. Exp. Metastasis, 10, 3-11, 1992) and in several other neuroendocrine neoplasms in man (Anthony, L. et al, Acta Oncol., 32, 217-223, 1993). Metabolism of somatostatin by aminopeptidases and carboxypeptidases leads to a short duration of action.

The actions of somatostatin are mediated via membrane bound receptors. The heterogeneity of its biological functions has led to studies to identify structure-activity relationships of peptides analogs at the somatostatin receptors which resulted in the discovery of five receptor subtypes (Yamada, et al, Proc. Natl. Acad. Sci. U.S.A., 89, 251-255, 1992; Raynor, K. et al, Mol. Pharmacol., 44, 385-392, 1993). The functional roles of these receptors are under extensive investigation. Binding to the different types of somatostatin subtypes have been associated with the treatment of the following conditions and/or diseases. Activation of types 2 and 5 have been associated with growth hormone suppression and more particularly GH secreting adenomas (Acromegaly) and TSH secreting adenomas. Activation of type 2 but not type 5 has been associated with treating prolactin secreting adenomas. Other indications associated with activation of the somatostatin subtypes are restenosis, inhibition of insulin and/or glucagon and more particularly diabetes mellitus, hyperlipidemia, insulin insensitivity, Syndrome X, angiopathy, proliferative retinopathy, dawn phenomenon and Nephropathy; inhibition of gastric acid secretion and more particularly peptic ulcers, enterocutaneous and pancreaticocutaneous fistula, irritable bowel syndrome, Dumping syndrome, watery diarrhea syndrome, AIDS related diarrhea, chemotherapy-induced diarrhea, acute or chronic pancreatitis and gastrointestinal hormone secreting tumors; treatment of cancer such as hepatoma; inhibition of angiogenesis, treatment of inflammatory disorders such as arthritis; chronic allograft rejection; angioplasty; preventing graft vessel and gastrointestinal bleeding. Somatostatin agonists can also be used for decreasing body weight in a patient.

In drug research, it is a key issue to minimize side effects by developing highly potent and selective drug molecules. Recent work on the development of nonpeptide structures (Hirschmann, R. et al, J. Am. Chem. Soc. 115, 12550-12568, 1993; Papageorgiou, C. and Borer, X., Bioorg. Med. Chem. Lett. 6, 267-272, 1996) have described compounds with low somatostatin receptor affinity.

The present invention is directed to a family of nonpeptide compounds, which are selective and potent somatostatin receptor ligands.

DETAILED DESCRIPTION OF THE INVENTION

One of ordinary skill will recognize that certain substituents listed in this invention may have reduced chemical stability when combined with one another or with heteroatoms in the compounds. Such compounds with reduced chemical stability are not preferred.

In general, the compounds of Formula I or II can be made by processes which include processes known in the chemical arts for the production of compounds. Certain processes for the manufacture of Formula I or II compounds are provided as further features of the invention and are illustrated by the following reaction schemes and examples.

In the above structural formulae and throughout the instant application, the following terms have the indicated meanings unless expressly stated otherwise:

The alkyl groups are intended to include those alkyl groups of the designated length in either a straight or branched configuration. Exemplary of such alkyl groups are methyl, ethyl, propyl, isopropyl, butyl, sec-butyl, tertiary butyl, pentyl, isopentyl, hexyl, isohexyl and the like.

When the definition “C₀-alkyl” occurs in the definition, it means a single covalent bond.

The alkoxy groups specified above are intended to include those alkoxy groups of the designated length in either a straight or branched configuration. Exemplary of such alkoxy groups are methoxy, ethoxy, propoxy, isopropoxy, butoxy, isobutoxy, tertiary butoxy, pentoxy, isopentoxy, hexoxy, isohexoxy and the like.

The term halogen or halo is intended to include the halogen atoms fluorine, chlorine, bromine and iodine.

The term cycloalkyl is intended to include a mono-cycloalkyl group or a bi-cycloalkyl group of the indicated carbon number known to those of skill in the art.

The term aryl is intended to include aromatic rings known in the art, which can be mono-cyclic, bi-cyclic or tri-cyclic, such as phenyl, naphthyl and anthracene.

The term heterocycle includes mono-cyclic, bi-cyclic and tri-cyclic systems having one or more heteroatoms, such as oxygen, nitrogen and/or sulfur. The ring systems may be aromatic, for example pyridine, indole, quinoline, pyrimidine, thiophene (also known as thienyl), furan, benzothiophene, tetrazole, dihydroindole, indazole, N-formylindole, benzimidazole, thiazole, and thiadiazole. The ring systems may be non-aromatic, for example pyrrolidine, piperidine, morpholine and the like.

The chemist of ordinary skill will recognize that certain combinations of heteroatom-containing substituents listed in this invention define compounds which will be less stable under physiological conditions. Accordingly, such compounds are less preferred.

When a chemical structure as used herein has an arrow emanating from it, the arrow indicates the point of attachment. For example, the structure

is a pentyl group. When an arrow is drawn through a cyclic moiety, the arrow indicates that the cyclic moiety can be attached at any of the available bonding points, for example

means that the phenyl can be bonded ortho, meta or para to the X group. When an arrow is drawn through a bi-cyclic or a tri-cyclic moiety, the arrow indicates that the bi-cyclic or tri-cyclic ring can be attached at any of the available bonding points in any of the rings, for example

means that the indole is bonded either through the phenyl portion of the ring or the nitrogen containing ring portion.

The compounds of the instant invention have at least one asymmetric center as noted by the asterisk in the structural formula (I), (Ia) and (Ib), above. Additional asymmetric centers may be present on the molecule depending upon the nature of the various substituents on the molecule. Each such asymmetric center will produce two optical isomers and it is intended that all such optical isomers, as separated, pure or partially purified optical isomers racemic mixtures or diastereomeric mixtures thereof, be included within the scope of the instant invention.

The instant compounds can be generally isolated in the form of their pharmaceutically acceptable acid addition salts, such as the salts derived from using inorganic and organic acids. Examples of such acids are hydrochloric, nitric, sulfuric, phosphoric, acetic, propionic, maleic, succinic, D-tartaric, L-tartaric, malonic, methane sulfonic and the like. In addition, certain compounds containing an acidic function such as a carboxy can be isolated in the form of their inorganic salt in which the counter-ion can be selected from sodium, potassium, lithium, calcium, magnesium and the like, as well as from organic bases.

The pharmaceutically acceptable salts are formed by taking about 1 equivalent of a compound of formula (I) or (II) and contacting it with about 1 equivalent of the appropriate corresponding acid of the salt which is desired. Work-up and isolation of the resulting salt is well-known to those of ordinary skill in the art.

Compounds of the instant invention can be and were assessed for its ability to bind to a somatostatin subtype receptor according to the following assays.

Human Somatostatin Subtype Receptor Binding Studies:

The affinity of a compound for human somatostatin subtype receptors 1 to 5 (sst₁, sst₂, sst₃, sst₄ and sst₅, respectively) is determined by measuring the inhibition of [¹²⁵I-Tyr¹¹]SRIF-14 binding to CHO-K1 transfected cells.

The human sst₁ receptor gene was cloned as a genomic fragment. A 1.5 Kb PstI-XmnI segment counting 100 bp of the 5′-untranslated region, 1.17 Kb of the entire coding region, and 230 bp of the 3′-untranslated region was modified by the BglII linker addition. The resulting DNA fragment was subcloned into the BamHI site of a pCMV-81 to produce the mammalian expression plasmid (provided by Dr. Graeme Bell, Univ. Chicago). A clonal cell line stably expressing the sst₁ receptor was obtained by transfection into CHO-K1 cells (ATCC) using the calcium phosphate co-precipitation method (1). The plasmid pRSV-neo (ATCC) was included as a selectable marker. Clonal cell lines were selected in RPMI 1640 media containing 0.5 mg/ml of G418 (Gibco), ring cloned, and expanded into culture.

The human sst₂ somatostatin receptor gene, isolated as a 1.7Kb BamHI-HindIII genomic DNA fragment and subcloned into the plasmid vector pGEM3Z (Promega), was kindly provided by Dr. G. Bell (Univ. of Chicago). The mammalian cell expression sector is constructed by inserting the 1.7 Kb BamHI-HindII fragment into compatible restriction endonuclease sites in the plasmid pCMV5. A clonal cell line is obtained by transfection into CHO-K1 cells using the calcium phosphate co-precipitation method. The plasmid pRSV-neo is included as a selectable marker.

The human sst₃ was isolated at genomic fragment, and the complete coding sequence was contained within a 2.4 Kb BamHI/HindIII fragment. The mammalian expression plasmid, pCMV-h3 was constructed by inserting the a 2.0 Kb NcoI-HindIII fragment into the EcoRI site of the pCMV vector after modification of the ends and addition of EcoRI linkers. A clonal cell line stably expressing the sst₃ receptor was obtained by transfection into CHO-K1 cells (ATCC) using the calcium phosphate co-precipitation method. The plasmid pRSV-neo (ATCC) was included as a selectable marker. Clonal cell lines were selected in RPMI 1640 media containing 0.5 mg/ml of G418 (Gibco), ring cloned, and expanded into culture.

The human sst₄ receptor expression plasmid, pCMV-HX was provided by Dr. Graeme Bell (Univ. Chicago). The vector contains the 1.4 Kb NheI-NheI genomic fragment encoding the human sst₄, 456 bp of the 5′-untranslated region and 200 bp of the 3′-untranslated region, clone into the XbaI/EcoRI sites of PCMV-HX. A clonal cell line stably expressing the sst, receptor was obtained by transfection into CHO-K1 cells (ATCC) using the calcium phosphate co-precipitation method. The plasmid pRSV-neo (ATCC) was included as a selectable marker. Clonal cell lines were selected in RPMI 1640 media containing 0.5 mg/ml of G418 (Gibco), ring cloned, and expanded into culture.

The human sst₅ gene was obtained by PCR using a λ genomic clone as a template, and kindly provided by Dr. Graeme Bell (Univ. Chicago). The resulting 1.2 Kb PCR fragment contained 21 base pairs of the 5′-untranslated region, the full coding region, and 55 bp of the 3′-untranslated region. The clone was inserted into EcoRI site of the plasmid pBSSK(+). The insert was recovered as a 1.2 Kb HindIII-XbaI fragment for subcloning into pCVM5 mammalian expression vector. A clonal cell line stably expressing the SST₅ receptor was obtained by transfection into CHO-K1 cells (ATCC) using the calcium phosphate co-precipitation method. The plasmid pRSV-neo (ATCC) was included as a selectable marker. Clonal cell lines were selected in RPMI 1640 media containing 0.5 mg/ml of G418 (Gibco), ring cloned, and expanded into culture. CHO-K1 cells stablie expressing one of the human sst receptor are grown in RPMI 1640 containing 10% fetal calf serum and 0.4 mg/ml geneticin. Cells are collected with 0.5 mM EDTA, and centrifuged at 500 g for about 5 min. at about 4° C. The pellet is resuspended in 50 mM Tris, pH 7.4 and centrifuged twice at 500 g for about 5 min. at about 4° C. The cells are lysed by sonication and centrifuged at 39000 g for about 10 min. at about 4° C. The pellet is resuspended in the same buffer and centrifuged at 50000 g for about 10 min. at about 4° C. and membranes in resulting pellet are stored at −80° C.

Competitive inhibition experiments of [¹²⁵I-Tyr¹¹]SRIF-14 binding are run in duplicate in polypropylene 96 well plates. Cell membranes (10 μg protein/well) are incubated with [¹²⁵I-Tyr¹¹]SRIF-14 (0.05 nM) for about 60 min. at about 37° C. in 50 mM HEPES (pH 7.4), 0.2% BSA, 5 mM MgCl₂, 200 KIU/ml Trasylol, 0.02 mg/ml bacitracin and 0.02 mg/ml phenylmethylsulphonylfluoride.

Bound from free [¹²⁵I-Tyr¹¹]SRIF-14 is separated by immediate filtration through GF/C glass fiber filter plate (Unifilter, Packard) presoaked with 0.1% polyethylenimine (P.E.I.), using Filtermate 196 (Packard) cell harvester. Filters are washed with 50 mM HEPES at about 0-4° C. for about 4 sec. and assayed for radioactivity using Packard Top Count.

Specific binding is obtained by subtracting nonspecific binding (determined in the presence of 0.1 μM SRIF-14) from total binding. Binding data are analyzed by computer-assisted nonlinear regression analysis (MDL) and inhibition constant (Ki) values are determined.

The determination of whether a compound of the instant invention is an agonist or an antagonist is determined by the following assay.

The reaction medium is removed and 200 ml 0.1 N HCl is added. cAMP is measured using radioimmunoassay method (Kit FlashPlate SMP001A, New England Nuclear).

The compounds of the instant invention are synthesized according to the following procedures and examples.

SYNTHESIS OF BROMOKETONES

General Procedure: Two different methods can be applied: starting either from a carboxylic acid or an arylketone.

First method: Starting from a carboxylic acid (Macholan, L.; Skursky, L., Chemistry, 1955, 49, 1385-1388. Bestman, H. J., Seng, F., Chem. Ber., 1963, 96, 465-469).

A carboxylic acid is first converted into an acyl chloride using oxalyl chloride or thionyl chloride or activated as a mixed anhydride with an alkylchloroformate (isobutylchloroformate (Krantz, A., Copp, L. J., Biochemistry, 1991, 30, 4678-4687) or ethylchloroformate (Podlech, J., Seebach. D., Liebigs Ann., 1995, 1217-1228)) in the presence of a base (triethylamine or N-methyl morpholine).

The activated carboxyl group is then transformed into a diazoketone using ethereal diazomethane or trimethylsilyldiazomethane (Aoyama, T, Shiori, T., Chem. Pharm. Bull., 1981, 29, 3249-3255) in an aprotic solvent such as diethyl ether, tetrahydrofuran or acetonitrile.

The bromination is then carried out using a brominating agent such as HBr in acetic acid, hydrobromic acid in water or in diethyl ether.

Preparation 1

1-Bromo-3-(4-chloro-phenoxy)-3-methyl-butan-2-one:

To a solution of chloro-4-phenoxy-2-isobutyric acid (2.15 g, 10 mmol) in 10 ml of anhydrous dichloromethane at about 0° C. were added oxalyl chloride (5.5 ml , 11 mmol of a 2M solution in dichloromethane) and DMF (2 drops, catalytic amount) via a septum under nitrogen atmosphere. The solution was stirred and allowed to warm up to room temperature over about 3 hrs. Concentration under reduced pressure afforded the crude acid chloride which was used directly without further purification.

The acylchloride was added dropwise at about 0° C. to a solution of TMSCHN₂ (11 ml, 22 mmol) in THF-acetonitrile (1:1, 10 ml). The mixture was stirred at about 25° C. for about 1 hour and then evaporated in vacuo.

A solution of the diazoketone in dichloromethane (10 ml) was added dropwise during about 10 minutes to a vigorously stirred mixture of concentrated hydrobromic acid (5 ml) in dichloromethane (20 ml). Nitrogen was evolved and a slight temperature rise occurred. After stirring for about a further 10 min., the mixture was diluted and the organic layer was washed with water (3 times 20 ml), dried over magnesium sulfate and evaporated. Flash chromatography of the residue eluting with AcOEt/Heptane (1:4) afforded the desired product with a yield of 79% (2.3 g).

¹H-NMR in CDCl₃ (100 MHz) δ: 7.05 (m, 4H, arom. H), 4.41 (s, 2H, CH₂), 1.53 (s, 6H, 2CH₃).

Preparation 7

1-Bromo-2-(3,4,5-trimethoxy-phenoxy)ethanone:

To a solution of 3,4,5-trimethoxyacetophenone (2.1 g, 10 mmol) in methanol (30 ml) was added pyridine hydrobromide perbromide polymer (1.4 eq). The resulting mixture was shaken at room temperature for about 2 hours and the reaction was stopped by filtration. The polymer was washed with methanol and the filtrate was evaporated in vacuo. The product was then purified by flash chromatography (AcOEt/Heptane, 1:4) affording 1.5 g (53%) of a white solid.

SYNTHESIS OF IMIDAZOYL COMPOUNDS

General Procedure: An amino acid is transformed to its cesium salt using cesium carbonate in a polar solvent such as DMF/H₂O (1:1) or EtOH/H₂O (1:1). An ester is then obtained using an appropriate bromoketone in a polar aprotic solvent such as dry DMF. The cesium bromide formed is filtered off and ammonium acetate is added in an aprotic solvent having a high boiling point such as xylene or toluene or in a protic acidic solvent such as acetic acid. The mixture is refluxed using a Dean-Stark trap for about 0.5-10 hours. In the scheme immediately below, PG is a protecting group, preferably a carbamate, such as t-Boc or benzyl carbamate.

EXAMPLE 1 2-{(1S)-1-[tertbutoxycarbonylamino]-2-[(1H)-indol-3-yl]ethyl}-4-(2-methoxyphenyl)-1H-imidazole

A solution of Boc-(D,L)-Trp-OH (10 g, 32.8 mmol) and cesium carbonate (0.5 eq., 5.34 g) in EtOH/H₂O (1:1, 70 ml) was shaken for about 30 minutes at room temperature, and then concentrated in vacuo at about 40° C.

To the resulting salt in 40 mL of dry DMF was added 40 ml of a solution of 2-bromo-2′-methoxyacetophenone (7.66 g, 1 eq.) in dry DMF. The mixture was stirred for about 1 hr at room temperature under argon and then concentrated under reduced pressure. Ethyl acetate was added (100 ml), the mixture filtered, and the CsBr washed with ethyl acetate. The filtrate was then concentrated under reduced pressure.

A solution of the foregoing filtrate and ammonium acetate (50.5 g, 20 eq.) in xylene (240 ml) was refluxed for about 3 hours at about 150° C. Excess NH₄OAc and H₂O were removed using a Dean-Stark trap. The progress of the reaction was monitored by t.l.c. (eluent: CH₂Cl₂:MeOH, 95:5). The mixture was then concentrated under reduced pressure. The resulting residue was dissolved in ethyl acetate (100 ml) and wash d with saturated aqueous NaHCO₃ solution until basic pH, and with brine until neutral pH. The organic layer was then dried over MgSO₄, and concentrated under reduced pressure.

Purification of the resulting residue by flash chromatography (eluent: CH₂Cl₂:MeOH, 95:5) afforded the desired compound (8.7 g, yield: 61%).

¹H-NMR (CDCl₃, 100 MHz) δ: 8.00 (s, 1H, NH), 7.80 (m, 2H, arom. H), 7.20 (m, 9H, arom. H, NH), 5.40 (m, 1H, NH), 5.10 (m, 1H, CH), 3.80 (s, 3H, OCH₃), 3.50 (m, 2H, CH₂), 1.50 (s, 9H, 6CH₃). LC/MS: m/z=433.3 (M+H).

EXAMPLE 2 N-[2-tertbutoxycarbonylamino ethyl]-2-{2-[(1S)-1-(tertbutoxycarbonylamino)-2-(1H)-indol-3-yl)ethyl]-1H-imidazol-4-yl}-isobutyramide

A solution of the 2-{2-[(1S)-1-(tertbutoxycarbonylamino)-2-(indol-3-yl)ethyl]-1H-imidazol-4-yl}-2-methyl-propionic acid-methyl ester 1 (2.6g, 6 mmol), (prepared according to the procedure described in Example 1) and LiOH.H₂O (1.7 g, 6.6 eq.) in THF (50 ml) were stirred at about 80° C. for about 3 hours. The progress of the reaction was monitored by t.l.c. (CH₂Cl₂:MeOH, 95:5). The resulting mixture was then concentrated in vacuo. About 50 ml of water was added to the residue which was then acidified with glacial acetic acid until about pH 5. The product of the reaction was then extracted with ethyl acetate (3×50 ml) and washed with brine until neutral pH. The organic layer was dried with MgSO₄, and concentrated under reduced pressure. The resulting intermediate 2 was obtained after crystallization in diethyl ether with a yield of 80% (29). ¹H-NMR (400 MHz, DMSO) δ: 10.9 (s, 1H, NH), 7.1 (m, 7H, arom. H, NH), 5.00 (m, 1H, CH), 3.3 (m, 2H, CH₂), 1.3 (m, 15H, 5CH₃). LC/MS: m/z=525.1 (M+TFA), m/z=413.2 (M+H).

The 2-{2-[(1S)-1-(tertbutoxycarbonylamino)-2-[(1H)-indol-3-yl]ethyl]-1H-imidazol-4-yl}-2-methyl-propionic acid 2 can be activated preferentially by carbonyldiimidazole in an aprotic solvent such as THF or DMF at about 20-100° C. for about 1-4 hours.

A solution of the acid 2 (1 g, 2.4 mmol) and carbonyldiimidazole (0.39 g, 2.4 mmol) in dry THF (20 ml) was shaken for about 1 hour at room temperature (25° C.).

N-Boc-ethylene-diamine (0.43 g, 2.7 mmol) was added and the mixture was shaken for about 1 hour at about 25° C.

The mixture was diluted in ethyl acetate (100 ml) and washed with saturated aqueous NaHCO₃ solution (2×50 ml) and brine until neutral pH. The organic layer was then dried over MgSO₄, and concentrated in vacuo.

Purification of the resulting residue by flash-chromatography (in CH₂Cl₂ :MeOH, 95:5) afforded the desired product 3 with a yield of 77% (1 g).

¹H-NMR (400 MHz, DMSO) δ: 11.6 (s, 1H, NH), 10.7 (s, 1H, NH), 7.00 (m, 9H, arom. H, NH), 4.8 (m, 1H, CH), 3.00 (m, 6H, 3CH₂), 1.3 (m, 24H, 8CH₃). LC/MS: m/z=667.3 (M+TFA), 555.3 (M+H).

SYNTHESIS OF AMIDES FROM IMIDAZOYL INTERMEDIATES

General procedure: Carboxylic acids are activated overnight at room temperature with carbonyldiimidazole in an aprotic solvent such as chloroform, THF or THF/DMF before addition of an amino starting material as shown above followed by a further 12-15 hours of stirring. The excess acylating agent is quenched with aminomethylated resin for about 12-15 hours and then purified on silica gel pad with dichloromethane or ethyl acetate as eluent.

For protected basic derivatives (R³=(CH₂)₄NHBoc and/or X² containing NHBoc group), the corresponding deprotected compounds were obtained after treatment under acidic condition (DCM/TFA 10%) to remove the Boc group.

From Carbamate Intermediates and Primary and Secondary Amines:

General Procedure: The preparation of carbamate intermediates is described in the literature (Takeda, K. et al., Tetrahedron Letters 1983, 24, 4569-4572; Nimura, N. et al., Anal. Chem. 1986, 58, 2372-2375) from amino derivatives and N,N′-disuccinimidylcarbonate in acetonitrile at room temperature.

EXAMPLE 4436 2-{(1R)-1-[(2,5-Dioxo-1-pyrrolidinyloxy)carbonylamino]-2-[indol-3-yl]ethyl}-4-phenyl-1H-imidazole (C₂₄H₂₁N₅O₄, MW=443.46)

302.4 mg (1 mmol) of 2-{(1R)-1-amino-2-[indol-3-yl]ethyl}-4-phenyl-1H-imidazole previously dissolved in 20 mL of anhydrous acetonitrile was added dropwise to a solution of N,N′-disuccinimidylcarbonate (528 mg, 2 mmol, DSC) in 20 mL of anhydrous acetonitrile during 1.5 hour. After a further 4 hours of stirring at room temperature, the solvent was evaporated in vacuo and the residue redissolved in 30 mL of chloroform. Excess DSC was then discarded and the organic layer washed with water (4×30 mL), dried over MgSO₄ and concentrated to obtain a brown solid (215 mg 49%). ¹H-NMR (CDCl₃, 100 MHz) δ: 8.22 (br s, 1H); 8.1-7.08 (m, 12H); 5.9 (br s, 1H); 4.97 (dd, J=3.6 and 9.3 Hz, 1H); 3.75 (dd, J=3.6 and 14.8 Hz, 1H); 3.06 (dd, J=9.7 and 14.6 Hz, 1H); 2.96 (s, 2H); 2.89 (s, 2H). LC/MS: m/z 329 ((M+H)-SuOH.

General procedure: A primary or secondary amine is stirred for about 2-15 hours at room temperature with a carbamate intermediate in an aprotic solvent like acetonitrile. Tetrahydrofuran and aminomethylated resin are then added and the reaction is then stirred for about 12-15 hours. Ureas are isolated after filtration, rinsed with ethyl acetate and evaporated in vacuo.

For protected basic derivatives (R³=(CH₂)₄NHBoc), the corresponding deprotected compounds were obtained after treatment under acidic condition (DCM/TFA 10%) to remove the Boc group.

SYNTHESIS OF AMIDINES BY CONDENSATION OF AN IMIDAZOLYL WITH THIOIMIDATES

A series of thioimidates were previously synthesized by condensation of thioamides and iodomethane in acetone at room temperature. The precipitate was collected and then rinsed with acetone. Thioimidates so formed were used without further purification.
